1.8L Supercharged SVHO Engine, 160mm pump

Yamaha four-cylinder, four-stroke, 1822cc, Super Vortex High Output (SVHO) marine engine delivers more power and torque than any WaveRunner in Yamaha range. Combined with a large 160mm hyper-flow jet pump and efficient intake, this engine produces 20% more power than its predecessor.






Integrated Speakers

All GP models come with Yamaha’s factory-installed, custom integrated Bluetooth marine audio system, which includes twin, powerful 4.5-inch fully waterproof marine speakers, integrated 2 channel (50 watts per channel) amplifier, easy access control pad and an integrated low-voltage regulator to protect the battery.






4.3″ Connext® Helm Control

All GP models come with Yamaha 4.3″ Connext ® helm control with a multi-color LCD display. An easily accessible touchpad control provides convenient access to the many functions including a PIN code security system and DRIVE ® Control that allows the owner to set top speed increments and acceleration settings from normal to slow.






Adaptable Steering System

Working closely with our pro riders we developed tilt-adjustable race-inspired, motocross style handlebars. You can keep them low for tight circuits or high for stand up and long distance riding.






Auto Trim

An industry-first auto trim function includes Cornering Control, which automatically shifts the trim into the bow down position when decelerating for tighter cornering and a racy feel, and Launch Control, which automatically shifts the trim down to prevent bow rise when accelerating quickly.






Enhanced Deck Design

The deck design provides improved ergonomics with deep and wide self-draining footwells, plus a narrow seat profile delivers improved knee and foot grip, and enhanced rider comfort.







Race Performance

The race designed top loader intake grate and jet pump allows less turbulent water to flow through the jet pump. The result is better acceleration and less cavitation in choppy water conditions.







Competition Steering and Handlebars

Our pro racers asked for it and we delivered! The exposed race style handle bars not only look fantastic, but offer four tilt-adjustable positions to suit every racing, stand-up and sit-down riding styles.






Multi-Mount Capability

All GP models come with a multi-mount base allowing you to connect action cameras, fish-finders and other devices, using third-party (purchased separately) multi-mount connection systems.







Ultra-Lightweight NanoXcel2

Yamaha’s cutting-edge NanoXcel2® ultra-lightweight hulls and decks are 18% lighter than the original NanoXcel®. This advanced material compound delivers exceptional performance properties resulting in significant improvements in acceleration, top-end speed, fuel economy, and handling.






Self Draining Footwells

The self-draining footwells prevent water pooling, including while in storage.







Three Person Sport Seat

The narrower race inspired two-piece, two-tone seat is ergonomically designed, textured and bolstered for grip, speed and comfort, suitable for recreational riding and racing. The seat comfortably seats three people. Separation of the front and rear sections makes maintenance and access to under-seat storage easy.






Large Rear Platform

Roomy and comfortable, the large rear platform is the ideal place for soaking up the surroundings, getting in and out of the water or simply doing nothing at all. The decking platform is fitted with custom cut Hydro-Turf mats for optimum looks, grip and comfort.






Reboarding Step

The GP1800 SVHO includes twin reboarding handles and an extra-deep ergonomically designed soft-touch reboarding step, making climbing back on board extra easy and safe.







Large Storage Capacity

The bow, glovebox, and under seat storage capacity has increased by 15% from the previous generation model, providing 107 litres of useable space. The bow compartment is easy to access and has a dedicated area for Yamaha’s cooler bag. The new water resistant glove box and under seat storage compartments include large openings for easier access and improved usability.






Integrated Dual Mirrors

Incorporating Yamaha trademark compact and edgy design styling, the integrated mirrors not only look good but aid rider visual awareness and overall safety.






Open Loop Cooling System

All Yamaha WaveRunners utilise open loop cooling, which is used by 99% of marine manufacturers. Open loop systems have been proven to be the most effective, reliable and maintenance free solution for marine environments, which means lower cost of ownership and less time off the water.
